Heat Recovery Solution Manufacturers and Products

Manufacturer	Description	Product Type
LG Electronics	LG Ventilation Solution ERV is an efficient solution for improving indoor air quality. The heat exchanger saves up to 24% more energy than natural ventilation and works with other features to provide total energy savings of up to 40%. The technology also features outdoor temperature sensing to adjust operation and a nighttime free cooling mode.	Airside Heat Recovery
Oxygen8	Ventilation solutions provide 100% fresh, filtered outside air to building occupants. The product lines include high-efficiency energy recovery, MERV-13 filtration, and integration with Daikin VRV heat-pump technology for heating and cooling.	Airside Heat Recovery
Ventacity	These ultra-efficient ventilation solutions provide excellent performance, reduced maintenance, greater operational efficiency while creating healthy, comfortable environments. Units boast energy recovery efficiencies of up to 93%, reducing both heating and cooling loads on other equipment and HVAC energy use.	Airside Heat Recovery
Renewaire	High-efficiency, static-plate, enthalpy-core ERVs utilize a highly developed air-to-air energy exchange core. The plates are made of an engineered “resin” material that simultaneously transfers heat through conduction and humidity by attracting bound water vapor from one airstream to the other.	Airside Heat Recovery
Swegon	Swegon airside heat recovery equipment uses a rotary heat exchanger to extract wasted energy from warm exhaust air, transferring heat to colder supply air, while also recovering moisture with a sorption-treated rotor.	Airside Heat Recovery
Aermec	Air-source and water-source heat pumps enable heat recovery through simultaneous loads, high temperature hot water, and modularity for chillers in retrofit applications. The NRB, and NRP product lines are air-source heat pumps, and the NXP, WWB, and WWM are water-source models.	Airside Heat Recovery
SHARC Energy	These wastewater heat recovery units are optimized for district energy, large commercial, and large multifamily use, ranging from 10 to 2,500 gpm of wastewater. The base model is able to recover thermal energy from wastewater streams for domestic hot water heating, while the HC model can also recover heat from a space cooling system to boost performance.	Wastewater Heat Recovery
Petra Engineering Industries	This energy recovery ventilator can be used as an air handling unit (AHU) or a dedicated outdoor air system (DOAS). Traditional energy recovery ventilation is accomplished with a cross-core heat exchanger, but Petra units also include an evaporator coil in the exhaust airstream, allowing DOAS operation nearly independent of the outside air temperature.	Airside Heat Recovery
Bulldog Heat Pump	This high-efficiency heat exchanger leverages heat rejected from a conventional water-cooled air conditioner to provide space heating via a fan coil. The compressors maintain cooling mode operation, but the heat pump can provide both cooling and heating year-round.	Water-cooled Air Conditioner, Hydronic Space Heater
LiquidCool Solutions	This full-immersion, direct flow, liquid tight chassis can be mounted directly to a server rack in a data center for electronics cooling. Heat removed from electronic components can be used for various applications: liquid to air (LTA) for space heating, and liquid to liquid (LTL) for hot water.	Process Heat Recovery
Carbon Cap	This high-efficiency condensing economizer can be retrofitted onto any commercial boiler and provides two times the heat transfer over competing systems. This results in greater boiler efficiency, reduced natural gas consumption, and lower carbon emissions.	Flue-gas Heat Recovery
Danfoss	The Danfoss Heat Recovery Unit (HRU) helps to eliminate the technical challenges of managing heat recovery. The HRU is an integrated solution managing and buffering the heat from the CO₂ refrigeration pack – to be reused for space heating, hot tap water, or redistributed to neighboring buildings.	Heat Recovery Unit
Showersave	Wastewater Heat Recovery (WWHR) units capture heat energy in the wastewater being sent down the drain. WWHR units recover heat by running cold mains water around the outside of the wastewater to extract heat through a counter flow heat exchange process. This reduces hot water demand by up to 50% and cuts energy consumption for water heating by one-third.	Wastewater Heat Recovery
Abora Solar	The second-generation hybrid solar panel (PVT) manufactured by Abora Solar is an effective solution for producing domestic hot water and electricity simultaneously. The copper absorber, with its lattice-like tube network, allows efficient circulation of the heat transfer medium, transferring heat in an optimal way. Meanwhile, the 72-cell photovoltaic laminate generates electricity in parallel with the production of thermal energy.	Thermal Storage
Naked Energy Ltd.	Virtu solar thermal collectors hold significant relevance as a building retrofit solution that enhances energy efficiency and reduces carbon emission. The low-profile design and adaptable installation options allow for installation on rooftops, facades, or ground-mounted arrays, maximizing available space and accommodating diverse building layouts and configurations. Virtu collectors can be utilized for a wide range of heat recovery applications, including domestic hot water heating, space heating, process heating, and humidity control.	Thermal Storage
HUBER Technology, Inc.	The HUBER ThermWin process allows heating and cooling of buildings by using the wastewater in the sewer system as a regenerative energy source. Sewer wastewater temperature is usually between 12° and 20° C, and hardly drops below 10° C even in winter, making wastewater an ideal energy source for operating a heat pump. This technology is applicable to all larger buildings and local heating networks.	Wastewater Heat Recovery
Armstrong World Industries	TEMPLOK Ceilings absorb and release heat to regulate indoor temperature and reduce energy usage. Energy Saving Ceilings combine phase change material (PCM) technology with standard Armstrong Ceiling panels. Just as in other applications, the PCM technology works within TEMPLOK Energy Saving Ceilings to cool and help regulate indoor temperature passively.	Thermal Storage
Energy Machines	Energy Machines makes it possible to combine heating, cooling, ventilation, and solar and wind power into one integrated system with unique benefits. Unlike traditional HVAC installations that are powered externally and operate separately within the same building, their integrated system generates, stores, and reuses its own energy.	Thermal Storage
Panasonic	Intelli-Balance® 100 is a powerful, high-performance, high-efficiency Energy Recovery Ventilator (ERV) that’s designed to help buildings meet ASHRAE 62.2 requirements. This unique and cost effective ERV was engineered for versatility and installation in any climate zone. Built-in controls minimize the time it takes to determine desired airflow, as well as verify and maintain performance.	Airside Heat Recovery
